This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

An introductory physics experiment has been developed to address the issues seen in conventional physics lab classes including assumption verification, technological dependencies, and real world motivation for the experiment. The experiment has little technology dependence and compares the acceleration due to gravity by using position versus time…

By modifying secret writing formulas uncovered from the archives of the East German Ministry of State Security (MfS or Stasi), a novel general chemistry secret writing laboratory was developed. The laboratory combines science and history that highlights several fundamental chemical principles related to the writing. These include catalysis, redox…

With the continual growth and demand of online courses, higher education institutions are attempting to meet the needs of today's learners by modifying and developing new student centered services and programs. As a result, faculty members are being forced into teaching online, including Earth and Space science faculty. Online Earth and Space…

Green chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Some of the philosophical questions and practical decisions that have guided the greening of the organic chemistry laboratory at Hendrix College in…

Describes an experiment to determine the density of air within a 10 percent error range using a basketball and a triple beam balance. Provides the typical data and a graph. (YP)

This paper describes the author's experience of designing and teaching an interdisciplinary course titled "Light", in collaboration with a visual artist. The goals of the course, texts used, laboratory work, art studio work, and other course activities are discussed with an emphasis on how light was used as a theme to make connections between…

Discusses forces that shape the behavior of water as a drop meanders down a windowpane. A homemade apparatus for studying meanders is described along with several experiments. Contact angles, molecule attraction, surface area, air tension, and gravity drag forces are some of the topics addressed. (DH)

Determines that the philosophical basis for science education is likely to be an interesting field in the 21st century and that there is a need to provide the practicing teacher with some ideas for daily work such as local, national, and international student cooperation; using student lab reports to develop local scientific journals; and having…

The purpose of this paper was to explore the concept of interest, one of the critical positive emotions in learning contexts and to investigate the effects of different types of visual illustrations on learning interest, achievement, and motivation in multimedia learning. The concept of interest was explored in light of positive emotion; an…

Discusses a demonstration of vertical collision of two balls. Shows the theoretical height ratio using mathematical expression and diagrams. Compares it with researchers' experimental results. Expands the two-ball collision to multi-ball system. (YP)

Discusses recent science studies that focus on experimentation and the implications of these studies for the philosophy of science. Argues that the results of scientific experiments are practical productions that embody practical solutions to some of the key problems that have worried science philosophers. (Author/WRM)

Proposes a simple procedure based on an expansion of the exponential terms of Raoult's law by applying it to the case of the benzene-toluene mixture. The results with experimental values are presented as a table. (YP)

A general discussion of prediction and the use of models as a means of understanding reality is provided, focusing on the application of mathematical models to various scientific disciplines and its role in experimentation. (DC)

Finds that interpretation of Galileo's only known experimental manuscript produces some interesting questions that offer pedagogical applications. Promotes classroom "research games" consisting of reconstructed experiments with Galileo's inclined plane and with other instruments to allow further speculation. (Author/WRM)
